Synthesis and structure of Na+-intercalated WO3(4,4′-bipyridyl)0.5

Abstract

WO3(4,4-bipyridyl)0.5 was doped with Na+ by ion implantation so as to alter the electronic structure. Single-crystal X-ray diffraction reveals layers of corner-shared WO5N octahedra linked by bipyridine. In the observed space group of Pbca, the fully-ordered bipyridyls form cages with Na+ disordered bimodally about the cage centre.
